Publically, Gulfstream seem to be talking most about the mid range right now, which is great business-wise. I get that -- they're running a for-profit organization.

But the 12-year-old in me wants to know what's next at the high end? Faster, farther, higher-tech, etc. etc.

I know the race is on for an SSBJ, and Gulfstream has been working hard behind the scenes developing and lobbying for their "QSJ" (Quiet Supersonic Jet), talking about the "Gulfstream Whisper" to get permission to fly supersonic over land.
